Detailed Description

The following are specific examples of the present invention, and the technical solutions of the present invention are further described with reference to the drawings, but the present invention is not limited to these examples, and the following embodiments do not limit the invention according to the claims. Moreover, all combinations of features described in the embodiments are not necessarily essential to the solution of the invention.

It will be understood by those of ordinary skill in the art that all directional references (e.g., above, below, upward, downward, top, bottom, left, right, vertical, horizontal, etc.) are illustratively used in the figures to aid the reader's understanding and do not imply (e.g., position, orientation, or use, etc.) a limitation on the scope of the invention, which is defined by the claims appended hereto. Additionally, the term "substantially" may refer to slight imprecision or deviation in conditions, amounts, values, or dimensions, etc., some of which may be within manufacturing or tolerance limits.

Example one

As shown in fig. 1, 2, 3, 4, and 5, a head protection cover includes a gas supply device 1 and a rectification device 2 located on both sides of the head, the gas supply device provides a pressure gas flow for the rectification device, and the rectification device includes a gas inlet 201 and a gas outlet 202.

Be provided with annular channel 203 in the air feeder, annular channel intercommunication gas outlet and air inlet, a lot of gas outlets are along annular channel circumference evenly distributed, and the gas outlet of gas flow evenly distributed to an orientation is passed through annular channel to the gas outlet, makes the gas outlet forms to use fairing to distribute as the radial at center to slightly to the orientation slope of head, make the gas flow that both sides fairing jetted out intersect around the head, form the air curtain 3 that surrounds the head, thereby play the effect of safety cover. The distance between adjacent air outlets can be flexibly changed adaptively according to the air outlet speed, so that the air discharged from two adjacent air outlets can be overlapped, the air outlets can also adopt flared holes, and the discharged air is diffused outwards in a fan shape.

The air flow in the rectifying devices positioned at the two sides of the head part is communicated through the transition air pipe 4, so that the air supply device only supplies air for the rectifying device at one side. The transition air pipe crosses over from the top of the head, and the transition air pipe is fixedly connected with the rectifying devices on two sides of the connecting head, so that the transition air pipe plays a role in bearing the weight of the rectifying devices.

The rectifying device is arranged on the ear muffs 5, so that the rectifying device is convenient to fix. The ear muffs are mute ear muffs and wrap up the ears completely, so that the influence of airflow noise is reduced. And a pull ring 6 is arranged on the rectifying device so as to be convenient to take and place.

As shown in fig. 6, the air supply device is integrated with a battery 7, an air filter element 8, an axial flow pump 9 and a controller for controlling the air supply amount of the air supply pump in a casing, so as to adjust the size of the air flow, the air supply pump is communicated with the air inlet of the rectifying device through a flexible air supply pipeline 11, so that the air supply device is an independent and movable filter, and is convenient to carry, and a control switch 10 can be arranged on the casing so as to control the air supply amount. Of course, various existing small air filtration devices can be used to provide clean air flow to the apparatus.
